Turn On 2-step Authentication In Gmail

This simple little step turns your phone into a security fob - in order for your Gmail account to be accessed from a new device, a person (hopefully you) needs a code that's sent to your phone. This means that even if someone gets your password somehow, they won't be able to use it to sign into your account from a strange computer. Google says that millions of people use this tool, and that "thousands more enroll each day." Be one of those people.
